On March 29 DHT and other classes went to the Science Fair in the hall some of them were about pressure , radiation and air. My favourite was the shadow light, all you have to do is stand in the closet then they close the door then there will be a flash of bright light then you turn around and you're shadow will stay still even if you move. They talked about atoms , gravity and fire. We also had the sit down so they can tell us about gravity and fire and it was amazing.
